        // 1、多行字符串
        let string1 = `Hey,
                        can you stop angry now?`
        console.log(string1)
        // Hey,
        // can you stop angry now?
        // 2、字符串插入变量和表达式。变量名写在 ${} 中，${} 中可以放入 JavaScript 表达式。
        let name = "Mike"
        let age = 27
        let info = `My Name is ${name},I am ${age+1} years old next year.`
        console.log(info)
        // My Name is Mike,I am 28 years old next year

        // 3、字符串中调用函数
        function f(){
            return "have fun!"
        }
        let string2 = `Game start,${f()}`
        console.log(string2); // Game start,have fun!
